SUBMERGED PUMP.

SPECIFICATION forming part of Letters Patent No. 226,019, dated March30, 1880.

' Application ledSeptember 10, 1879.

To all whom it may concern:

Be it known that we, WALTER O. BEEBE, FRED. B. DrcKEY, and CHARLES W.BARNES, all of Belmont, in the county of Allegany and State of New York,have jointly invented certain new and useful Improvements in SubmergedPumps; and we do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the let ters of referencemarked thereon, whichform a part of this specification.

Our invention embraces improvements in submerged double acting forcepumps, in which non-corrodible cylinders are used. The entire submergedand working parts are rendered non-corrosive, which is an importantadvantage, as it not only increases the durability of the pump, butpreserves the normal taste of the water.

The cylinders are of vulcanized rubber, and the connecting` andoperating meta-l parts are vulcanized rubber coated, so that, inconnection with a non-corrodiblev cylinder, the valve and the plungerparts are likewise rendered free from corrosion, whereby metal valvesmay be used without rusting. The plunger-packing forms also the seat forthe valve, which is a disk, and opens and closes upon said seat within askeleton cap, the packing having a cup form with its upper edges,makinga close workin g with the cylinder, and the valve, when closed,forming the bottom of the cup and resting upon the inner or bottom partof said packing.

The cylinders are united at their upper ends by an arched screwway-pipe, into which each cylinder is separately screwed, while thelower ends of the cylinders are braced and supported by clampingyoke-straps, which also form guides for the plunger-rods.

The pump is suspended from a point above the cylinders by means ot' awooden stud, the upper end of which forms a saddle on which thevcoupling-cap rests, and is secured to said stud between the cylinders,the lower ends of which are also secured to said stud by theyoke-straps, whereby the cylinders are balanced and the working oftheplungers rendered free from unequal binding.

Referring to the drawings, Figure l represents a side view of ourimproved pump; Fig.

2, a vertical section ofthe same; Fig. 3, a horizontal section, showingthe cylinder yoke-straps and plunger-rod guides; and Fig. 4, a sectionof the plunger on an enlarged scale.

The cylinders stand vertically in the water,

and the valved plungers are operated through 6o tends above the well, atthe bottom of which the pump is placed and supported by the wooden stud.The cylinders are of vulcanlzed rubber cast in a steel mold, and haveperfectly smooth and true inner walls. Both ends are open alike, and oneend has formed there- 7o on an exterior screw, a, by which it isconnected with interior screw-threaded lap-rims b of the coupling-pipec, said lap-rims being of a sufficient depth to give a firm and brac-Iing support for the cylinders, and by this means avoid separatescrew-bolt fastenings. The way-couplings c has check-valves d at its,union with the cylinders, and the dischargepipe e is screwed centrallyinto said coupling.

The seat for the check-valve is formed by a 8o plate, f, which forms thetop of the cylinder, and is clamped thereon with a gasket of the valveby the screw lap-rims. The cylinders are united and supported at their.lower open ends by clamping yoke-straps g, which, em-

bracing each cylinder, are bolted together and to a central woodensupport, A, by the bolt h', the point of which, being lforced into thebottom of the well, holds the pump in place.

Upon this central support the pump is sus- 9o tained at al point abovethe cylinders by seating the coupling-pipe c upon said support, wherebythe cylinders are suspended from and on each side of said support inperpendicular positions and the plun gers caused to work free g5 fromunequal binding. At the point of suspension the coupling-cap c hasprojection h, which pierces the saddle end of the wooden support, and issecured toit by a bolt, h.

The plunger consists of two parts, between 10o which the packing li isclamped ina manner to give it a concave or cup form. One of these partsforms a base-ring, j, and the other the skeleton cap, k, within which adisk-valve, l, is confined, and these two parts are secured together bywrought-iron screw-bolts m, which, being molded within the cap part,project through the base-ring, and by means of nuts m' serve to secureit to the plunger-rod. The upperouter edge of the packing extends overand beyond the base-ring, and forms a close working with the cylinder,while the inner lower edge of the packing forms a gasket-seat, i', forthe valve and gives a closejoint. 'In this particularthetplunger-packing serves a new function by extending its linner edgewithin the valve-cap and supportingit upon the basering j to form thevalve-seat. The plungerrods p connect with a top operating-lever, q, bya cross-head, 1, pivoted in a casting, s, to which the discharge-pipe isclamped at the top of the well. Any suitable operating connection may beused.

The yoke-straps for the cylinders are utilized to form guides g' for theplunger-rods, to keep them steady and the plungers free from wabblingand unequal wear.

The coupling-cap c and the discharge-pipe e are vulcanized rubbercoated. So, also, are the plunger parts, the valve, and the plungerrods.In fact, all the water-covered parts are rendered non-rusting, givinggreater durability to the pump, and especially preserving a smoothpacking-surface in a metal valve.

In the operation of the pump one cylinder is filling while the other isdischarging, and both discharge upwardly through the check-valves intothe coupling-cap'and out the dischargepipe in a continuous stream.

The packing z may be of stout leather or of india-rubber, and forms,with the base-ring,

the plunger proper, so that in forcing the water up the packing ispressed out close against the cylinder, with the valve closing tightlythe central opening in the base-ring, while in the descent o'f theplunger the valve rises and the packing-edge is contracted, so that theplunger has in its descent little or no friction upon the cylinder.

We claiml. The plunger-packin g forming the circumferentialwater-lifting part z' and the seat i' for the valve Z, and clamped incup form by and between the open valve-cap 7c and base-ring j,substantially as herein set forth.

2. The plunger consisting of the base-ring j, the open cap lc, and thepackingfit, clamped together and to the plunger-rods 19 by the screws m,molded in the cap part, and in which the valve l has its seat upon theinner packing part vl', all substantially as herein set forth.

3. A submerged pump of two cylinders, supported by the intermediatewooden stud, A, at a point above said cylinders, by their coupling-cap,to which said support is secured, in combination with the yoke-straps g,connecting and bracing the lower open ends of' the cylinders with saidstud-support, substantially as herein set forth.

4. The guides g for the plunger-rods l), formed by the yoke-straps g, inthe manner and for the purpose herein set forth.

In testimony that we claim the foregoing we have hereto atxed oursignatures in the presence of two witnesses.
